Playlist Switching via Time-Axis Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In recording reproduction apparatuses, combining multiple play lists for a single content, such as goal scene and cheering scene lists, results in overlapping segments on a time axis, making it difficult for users to understand and utilize effectively.
Innovation Solution
Implementing a method where the play list reproduction unit controls the switching between play lists by starting from the reproduction segment closest to the stop time of the previous list, allowing users to intuitively recognize which play list is currently being reproduced and enabling easy switching between them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple play lists are combined and presented together, then the quantity of information is increased, but the ease of understanding and utilization deteriorates due to overlapping segments on time axis
Solution Approach 1:
The patent segments the time axis into distinct non-overlapping intervals for each play list. By dividing the time dimension into separate segments, multiple play lists can be displayed simultaneously without overlapping, making each play list's timeline clear and easy to understand while maintaining the ability to present multiple play lists together.
Solution Approach 2:
The patent introduces a new dimension for displaying play lists by arranging them in parallel time intervals rather than overlapping on a single time axis. This dimensional change allows multiple play lists to be presented in a structured, non-overlapping manner, improving understandability while preserving information quantity.
2Device complexity
If play lists are displayed with overlapping segments on time axis, then the device complexity is reduced, but the ease of operation worsens due to difficulty in understanding
Solution Approach 1:
The patent applies segmentation to divide the time axis into distinct intervals for each play list. This creates a simplified display structure where each play list occupies a separate time segment, reducing the complexity of managing overlapping timelines while simultaneously improving user understanding of each play list's progression.
3Adaptability or versatility
If reproduction switches from first play list to second play list, then the adaptability is improved, but the loss of time increases due to discontinuity in reproduction flow
Solution Approach 1:
The patent implements preliminary action by pre-calculating and storing the time points where each play list's reproduction segments align with the stop time of the previous play list. When switching between play lists, the system uses this pre-prepared information to automatically resume from the most appropriate segment, minimizing time loss and maintaining smooth reproduction flow across different play lists.
Solution Approach 2:
The patent employs feedback mechanisms to track the stop time of the currently reproducing play list and use this information to determine the optimal restart point in the next play list. This feedback loop ensures that play list switching maintains temporal continuity and reduces unnecessary time loss while preserving the ability to switch between different play lists.

AI summary
Apparatus and method for information processing may control reproducing from a play list. When reproducing is switched from a first play list to a second play list, the play list reproduction unit controls reproducing from the second play list to start from a reproduction segment of the second play list having a start time closest to a time point at which the reproducing from the first play list is stopped when the reproducing is switched from the first play list to the second play list.
